What is OAuth?
A standard that lets you log into apps using your existing accounts from Google, Facebook, or other providers
Why It Matters
OAuth makes it easier for users to sign up (no new password to remember) and can be more secure than managing passwords yourself
Real-World Example
Clicking 'Sign in with Google' on a new app instead of creating a new account
